Filters cleaning

At the conclusion of the settling, the water is steered towards filters of homogeneous sand and bicouches filters (sand - activated charcoal) that allow to distribute the elimination of suspension materials on 2 materials of different grading sizes: for the same filtering surface, these works allow the treatment of a more important flow.
Filters are cleaned by a wash of air and water made against the current.
The automatism determines the order of filters wash according to their degree of sealing and activate the operations of wash and rinsing.
